David Costanzo 20208cc81f Fix loading bitmaps with malformed biClrUsed field
Stop throwing std::bad_alloc when BMP has large/negative biClrUsed by
checking that biClrUsed has a reasonable value before attempting to
allocate however much memory it indicates.

Add unit tests showing the loading such invalid bitmaps now correctly
returns an error rather than throwing an exception.
